Hey hunters 👋
I built CalcDock because I was tired of the same thing every time I needed a quick calc on my phone — landing on some ad-choked website, waiting for it to load, closing three pop-ups just to find a mortgage or BMI calculator.
So I built the opposite: 151 calculators in one fast app — everyday math, finance, health, science, engineering — searchable from the home screen, no ads blocking the actual calculator (ads only show after you leave a free calc, never on the basic one), dark mode built in.
110 calculators are free, no account needed, nothing collected. The other 41 (mortgage/refinance, retirement & investing, scientific/engineering, health pro) are one-time purchases — buy a pack once, own it forever. No subscriptions, no "free trial" that quietly bills you later.
It's the mobile companion to realonlinecalculator.com — same calculators people already trust, now native and fast instead of a slow, ad-heavy page.
Right now it's only for Android - https://play.google.com/store/apps/details?id=com.realonlinecalculator.calcdock
Would genuinely love feedback on:
- What calculator category you'd want added next
- Whether the free tier feels generous enough, or premium pricing feels off
Thanks for checking it out — happy to answer anything below 🙏
